Pendulum Lab

  1. Nov 25, 2007 #1
    I did a pendulum lab and determined that length affected the period. So the values got where:

    10 cm = 6.47 s
    15 cm = 7.895 s
    20 cm = 8.94 s
    25 cm = 9.89 s
    30 cm = 10.5 s
    35 cm = 11.905 s

    With these values, it seems like graphing this straight as it is results in a linear line, but I searched around and found that others did period^2 vs. length.

    What should I do?

    well the equation for the period of a pendulum is given by
    [tex]T=2\pi\sqrt{\frac{l}{g}}[/tex]

    so can plot T^2 vs. l or plot T vs.sqrt{l} and you'll get it

    Which equation should I use to describe the T^2 graph. My friend said it includes length, acceleration, and radius.

    Well both are the same...if you plot T^2 vs. l the gradient of that graph would be [itex]\frac{4\pi^2}{g}[/tex] and you can find g from there

    Hey plz help me out here ...i m in grade 11 and i got this assignmnt ..where i have to design a car that will move forward from a suspended mass...i hav no idea wot to do ... itz due this frdayplzz i really need help...none of my grou members are helping me out ..

    He said it was l=a/r since the T^2 graph is linear and the slope of that graph is the acceleration, is he right?
